Rookery

A rookery is a colony of breeding animals, generally birds.[1] A rook is a Northern European and Central Asian member of the crow family, which nest in prominent colonies (multiple nests) at the tops of trees.[2] The term is applied to the nesting place of birds, such as crows and rooks, the source of the term. The breeding grounds of colony-forming seabirds and marine mammals (true seals or sea lions) and even some turtles are also referred to as rookeries.

The term rookery was also borrowed as a name for dense slum housing in nineteenth-century cities, and especially London.[3]

Paleological evidence points to the existence of a pterodaustro rookery.[4]
